“For our business customers, 4G is all about working more effectively.

“They can work remotely, access cloud services, collaborate using apps and so on. 4G will make everything easier for them.”

O2 is spending £600m in 2015 on its network and by the end of 2017 will have invested over £3bn in 4G and the modernisation of its 2G and 3G networks across the UK.
